Description


beford has discovered a vulnerability in V-webmail, which can be exploited by malicious people to compromise a vulnerable system.

Input passed to the "CONFIG[pear_dir]" parameter in "includes/mailaccess/pop3.php" isn't properly verified, before it is used to include files. This can be exploited to include arbitrary files from external and local resources.

Successful exploitation requires that "register_globals" is enabled and that the "includes" directory is placed accessible inside the web root (the installation instructions recommends to place the "includes" directory outside the web root if possible)

NOTE: In version 1.3 then the affected script is reportedly named "includes/mailaccess/pop3/core.php".

The vulnerability has been confirmed in version 1.6.4, and has also been reported in versions 1.3 and 1.5.


Solution:
Ensure that only the "htdocs" directory is accessible inside the web root.
